## 1. Technical Specifications
The "M.2" designation refers to the physical dimensions and the pin configuration. Below are the electronic and mechanical characteristics typical for this specific series:
| Property | Description |
| :--- | :--- |
| **Connector Type** | M.2 (NGFF) Card Edge Connector |
| **Orientation** | Right Angle / Surface Mount (SMT) |
| **Number of Positions** | 67 Pins |
| **Pitch** | 0.50 mm |
| **Keying** | Typically **Key M** (often used for NVMe SSDs) |
| **Mounting Height** | 4.2mm (indicated by the '42' in the suffix) |
| **Contact Plating** | Gold (R/N usually indicates RoHS compliance and specific plating thickness) |

## 2. Key Electronic Features
### A. High-Speed Signal Integrity
These connectors are designed to handle high-frequency signals. The **M2AS1** series supports:
* **PCIe Gen 3 & Gen 4:** Capable of handling high data rates required for NVMe storage.
* **SATA 3.0:** Backward compatibility for slower storage modules.
* **USB 3.0/4.0:** Integration for wireless communication modules.
### B. Pin Configuration
The 67-pin layout is divided into sections by a "key." The key prevents the user from inserting the wrong type of module (e.g., preventing a Wi-Fi card from being forced into an SSD-only slot).
### C. Mechanical Stability
* **Standoff Height:** The 4.2mm height provides clearance for components mounted on the underside of the M.2 module.
* **Solder Tabs:** Includes metal ear-tabs for mechanical grounding and to ensure the connector does not rip off the PCB under stress.
